By Caroline Arbanas, Washington University in St. Louis Scientists have decoded the DNA of the parasitic worm that causes trichinosis, a disease linked to eating raw or undercooked pork or carnivorous wild game animals, such as bear and walrus. After analyzing the genome, investigators at Washington University School of Medicine in St. Louis and their collaborators report they have identified unique features of the parasite, Trichinella spiralis, which provide potential targets for new drugs...

The team found that a bacterium inside the worm acts as a 'disguise' for the parasite, resulting in the immune system reacting to it in an ineffective way. The bacteria protect the worm from the body's natural defences, but once the bacteria are removed with antibiotics, the immune system responds appropriately, releasing cells, called eosinophils, that kill the worm. Antibiotics are successful against the parasite, but the long treatment regime means that it has limited use across whole...

In a major breakthrough that comes after decades of research and nearly half a billion treatments in humans, scientists have finally unlocked how a key anti-parasitic drug kills the worms brought on by the filarial diseases river blindness and elephantitis. Understanding how the drug ivermectin works has the potential to lead to new treatments for the diseases, in which the body is infected with parasitic worms, said Charles Mackenzie, a professor of veterinary pathology in the College of...

How parasites use different life-history strategies to beat our immune systems may also provide insight into the control of diseases, such as elephantiasis and river blindness, which afflict some of the world's poorest communities in tropical South-East Asia, Africa and Central America. The research is due to be published next week in the online, open-access journal PLoS Biology. The study, led by Dr Simon Babayan of the University of Edinburgh, showed using a mouse model of parasite...

University of Rochester biologist documents novel form of adaptation through natural selection in the journal 'Science' It has been a basic principle of evolution for more than a century that plants and animals can adapt genetically in ways that help them better survive and reproduce. Now, in a paper to be published in the journal Science, University of Rochester biologist John Jaenike and colleagues document a clear example of a new mechanism for evolution. In previous well documented cases...

Deworming lambs can be minimized with rotational grazing and checking the animals' eye color, according to an Agricultural Research Service (ARS) study. Animal scientist Joan Burke at the ARS Dale Bumpers Small Farms Research Center in Booneville, Ark., and colleagues made this finding as part of a continuing collaboration with scientists, veterinarians, and extension agents from the Southern Consortium for Small Ruminant Parasite Control. The consortium was formed in response to the threats...

Community-based lymphatic filariasis education in Orissa State, India, increased treatment compliance from around 50% to up to 90%, according to a study published June 29 in the open-access journal PLoS Neglected Tropical Diseases. In their study, researchers from the U.S. Centers for Disease Control and Prevention, in partnership with the Church's Auxiliary for Social Action, an India-based non-governmental organization, and IMA World Health, a US-based non-governmental organization,...

Nematology
2013-09-30 13:49:26

Nematology is the study of nematodes, also known as roundworms, which first began in the nineteenth century. Like many fields of study, nematology began with ancient recordings and descriptions lacked elements of modern science. The oldest record of a nematode occurs in the Pentateuch in the fourth book of Moses known as Numbers. The reference, although not plainly stating roundworms or nematodes, is thought to refer to Dracunculus medinensis, a species that is native to the area near the Red...

Trichuris suis
2014-01-12 00:00:00

Trichuris suis is a species of whipworm that is classified within the Nematoda phylum. It can be found in warm tropical regions throughout the world but is rare in arid regions. Males reach an average body length between 1.1 and 1.5 inches, while females reach an average length between 2.3 and 3.1 inches. This species, and other members of the Trichuris genus, was given its common name because of its whip like appearance. The original definitive hosts of this species are pigs, but it is able...

Phasmarhabditis hermaphrodita is a species of roundworm that is classified within the Nematoda phylum. This species is found in soils where slug species from the Limacidae, Arionidae, and Milacidae families are located, with one common host being Deroceras reticulatum. The worm can be located in soil by using real-time PCR testing methods, a test that also distinguishes it from its similar relative, Phasmarhabditis neopapillosa. The life cycle of Phasmarhabditis hermaphrodita begins in...

Onchocerca volvulus
2014-01-12 00:00:00

Onchocerca volvulus is a species of roundworm that is classified within the Nematoda phylum. This species causes the disease onchocerciasis, more commonly known as river blindness. The life cycle of this species is dependent upon an intermediate host, typically the black fly, and a definitive host, which is always a human. Its lifecycle begins when a black fly ingests microfilariae from a human host by consuming blood. The microfilariae that were present in the skin of the human host now...

Trichinella spiralis
2014-01-12 00:00:00

Trichinella spiralis, sometimes known as the pork worm, is a parasite within the Nematoda class. It can be found in pigs, rats, humans, and bears. This worm causes trichinosis in humans, most often from consuming undercooked pork. This species is the smallest within its class, reaching an average body length of .16 centimeters. Females are twice as large as males, displaying a sexual dimorphism. The reproductive organs of females are unique to the species in that the front end holds developed...
